The Ten Commandments existed before Sinai. Rachel knew not to steal, Cain knew not to kill, Joseph knew not to sleep with married girls. Stop being legalistic, for heaven's sake.
The law of sin and death aint the Ten Commandments, which Paul calls "holy, just, and good", remember? The same law can't be both that and "sin and death" unless one attempts to attain righteousness by keeping the law.
So, Christians may kill, steal, lie, etc. Got it.
And Eureka, you've discovered how it is that we may keep the commandments: by allowing Christ to come into our heart and keep them for us. Bingo. That's why John says those who refuse to keep the commandments of God are liars and bankrupt of the truth.
You antinomianists have been so seduced by Satan into believing error that you cannot discern the difference between the "reasonable service" of obedience with the "impossible service" of earning salvation by keeping the law. NO ONE CAN KEEP THE LAW UNLESS CHRIST IS IN HIM.
How is it that you deny what the Spirit has said to the churches? That we "can do ALL THINGS through Christ". Is English your first language? Do you understand what "ALL THINGS" means? It means "ALL THINGS", period. The reason why you can't stop watching pornography is not because you CAN'T, it's because you DON'T WANT TO. Christ loves you and stands ready to give you the victory - all you gotta do is just ask and He will give you the power to resist the devil...every...single...time.
I preach "grace". You preach "disgrace". You preach that Christians are "more than conquerors" while getting a Beelzebub beat down every time he comes around to dangle his temptations before their faces. Conquerors who forgot to tell the enemy they supposedly conquered, right? How utterly pathetic. The reason you Antinomianists can't get victory over sin is because you refuse to make a full surrender to Christ, that He may impart to you power to be true overcomers and conquerors. It's time that you Antinomianists stand up, wipe your sniveling little noses, and take a stand against the devil.
